LOCOMOTIVE HEAD-LIGHT.

SPECIFICATION forming part of Letters Patent No. 270,792, dated January16, 1863.

Application filed November 28, 1882.

To all whom it may concern Be it known that we, ARTHUR HARRIS and GEORGEM. CLARK, both of Chicago, in the county of Cook and State of Illinois,have invented certain Improvements in Locomotive Head-Lights,of whichthe following is a specitication.

This invention relates to improved means for exhibiting signals onlocomotive head- I0 lights; and,'briefly considered, it consistsintransmitting light from the interior of the lantern by reflectionthrough bulls-eyes or signal-glasses placed at the front of theheadlight, as hereinafter set forth.

In the accompanying drawings, Figure 1 is a side view of our improvedhead-light. Fig.

2 is a front view thereof. Fig. 3 is a sectional plan on the line x 00of Fig. 1.

Similar letters of reference indicate similar parts in the respectivefigures.

A is the exterior case of the head-light or lantern, and a its rim. B isa box, adapted to be secured removably or permanently to the upper partof the rim a by means of a bracket,

b, at the rear of the box. The lower portion of the rear side of saidbox is open, as shown ate, and confronts the main reflector within thelantern. The bottom (I of the box B is carried up at an outward anglefrom the face 0 of the rim, and at its inner side is provided with arefiector,d. The box B is furnished with a front signal-gass, e, andsimilar side glasses, 6. The glasses are shown of the ordinary bulls-eyeclass; but they may, it de- 5 sired, be flat and of rectangular outhneand bear a number or other mark.

Placed above the reflector d is another reflector, d, at an anglepractically parallel to the surface of the reflector (1. As shown in 0Figs. 2 and 3, the reflector d" is made to increase in width toward itstop. Other reflectors, d d, are also placed within the box B,

which, as seen in Figs. 1 and 2, are confined between the back of thereflector d and the rear wall of the box B, extending by preferencesomewhat above the top edge of the reflector d. As shown in Figs. 2 and3, the reflectors d join at their lower edges, extending upward atopposite outward angles. The reflector d is designed to cover the entire5 area of the inner side of the bulls-eye c, and the reflectors d thatof the bullseye c 0'. Light thrown from the main reflector within thehead-light or lantern will strike the reflector d, as indicated by thearrow in Fig.1, 5-5 and will'then be thrown upon the reflectors d d dthrough the respective bulls-eyes or signal-glasses. Y

The glasses may be made removable for the This invention can be appliedto any headlight now in ordinary use.

We claim as our invention- 1. Combined with a locomotive head-light,

a box secured to the head-light rim,having an 6 opening extending withinthe margin of the rim, and confronting the main reflector, and furnishedwith interior reflecting-surfaces and signal-glasses, substantially asset forth.

2. The box B and bracket 1), combined with the head-light A and rim to,substantially as set forth.

3. The box B, having signal-glasses e c e, reflecting-surfaces d d d d,and the opening 0, combined with a locomotive head-light, substantiallyas set forth.
